MEANS FOR PROPELLING VESSELS.

srncrrrcnfrron forming part of Letters Patent No. 649,781, dated. May15, 1 90o.

Application filed October 27, 1899.

To @ZZ whom t 71mg/ concern.-

Be it known that I, ANTONIO VOLTOR, manufacturer, residing at Barcelona,in the Province of Barcelona and Kingdom of Spain, have invented certainnew Vand useful Improvements in Means for the Propulsion of Vessels; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, suoli as will enable others skilled in theart to which it appertains to make and use the same. p K l Thisinvention relates to improvements in means for the propulsion of shipsor the like, more especially to that class of ships using sidepropellers which are entirely submerged.

In order to more fully explain the said invention, reference will be hadto the accompanying drawings, in which- Figure lis a longitudinalsection of the invention as applied to the side of a ship. Fig. 2 is anend view showing parts in section on the line :c oz, Fig. 1. Fig. 3represents a transverse section on the line e z, Fig. l. Fig. a is aview showing the construction of the end of the main or driving shaft,and Fig. 5 is a longitudinal section of the same.

Similar parts are indicated by the same letters and numerals ofreference throughout the several views, in whichd, Fig. l, designatesthe main or driving shaft, formed at one end with an enlarged portion.

b designates the propeller-blades, each of which is provided with asocket o'.

The enlarged portion of the shaft a is provided with a removable plug orcap c, which allows the small transversely-disposed rockshaft CZ to beplaced into position.

e designates a slotted circular disk rigidly secured upon the rock-shaftd.

cl' CZ are reduced portions of the rock-shaft d, and are adapted toenter the sockets b' upon the propeller-blades b, and are securedtherein by means of the keys ZJ.

Running longitudinally of the shaft a and at opposite sides of the saidshaft are the grooves Z, into each of which fits a rod or bar f. Uponone end of each of these rods or bars is a stud 7u, each of which entersone of the elongated openings e in the disk c. Upon the other end ofeach of these rods or bars is provided another stud g, both of thesestuds Serial No. 734,982. (No model.)

following the cam-groove t in the bushing t as the main or driving shafta is rotated, one of said studs resting in said cam-groove diametricallyopposite tothe other. The bushing t is fitted snugly upon the shaft aand is supported in the bearing formed by the parts 4 and 5. Thisbushing acts as one of the bearings for the shaft a and is provided witha toothed crown t, which is engaged by the worm-wheel It, the hand-wheel7L being provided for rotating the said worm-wheel, and thereby rotatingthe bushing t.

n n represent portions of a stuffing-box, the part n being secured tothe bushing t and the portion n being secured upon the bearing t', towhich is attached the journal-bearing i. To the other end of the bushingt is secured the stuffing-box n" upon the inner end of the main ordriving shaft d.

m shows an oil-conduit which runs longitudinally of the shaft a andcommunicates with the transverse shaft d and with the transverse conduito.

The operation is as follows: Power being applied to the shaft a from anysuitable source, the shaft a is caused to revolve, say, in the directionof the arrows, Fig. 2. The revolving of the main shaft carries with itthe rods f, thereby causing the studs g to follow the canigroove t inthe bushing t. This causes the rods to reciprocate first in onedirection and then in the opposite direction, the relative positions ofthese rods being such that they reciprocate in opposite directions. Thisreciprocating movement of the rods f causes the studs 7c thereon torotate the annular disk e first one-quarter of a revolution and then thesame distance in the opposite dil rection. The shaft d being rigidlyattached to the disk e, the rocking motion imparted to it will also beimparted to the rock-shaft, which finally imparts its motion to thepropeller-blades. These blades are secured upon the shaft d in such amanner that the flat portion of the blade of one propeller is parallelwith the plane of rotation of the shaft a, while the other blade is atright angles thereto. By means of the rods f, reciprocated by thecani-groove t and acting upon the circular disk e, these blades arecaused to rotate, so that when the shaft is revolving in the asu sumeddirection each blade is caused to ron IOO tate in such a manner as tooffer the flat side of the blade to the water below the drivingshaft andto propel the ship along, while the blade upon the opposite end of theshaft d is passing through the water edgewise, offering very littleresistance. This same motion is repeated each time'that the main shaftmakes a revolution, as will be obvious, thus causing the ship to move inone direction.

I provide a novel means for reversing the direction of the vesselwithout reversing the direction in which the main or driving shaftrevolves, which I will now describe.

Referring to Fig. 3, it will be vseen that the bushing t is rotatablymounted in the bearing 4 5. By turning the hand-wheel 71, this bushingis caused to rotate, which motion is continued until it has rotated onehundred and eighty degrees or half a revolution. It will be seen thatthis rotation has changed the positiony of the cam-groove t', so thatinstead of the blades propelling the water below the main shaft, as wasassumed in the previous ease, they will now be propelling the waterabove the shaft, or, in other words, the reaction of the water upon thepropeller will be reversed while the driving-shaft a continues torevolve in the same direction.V

Lubrication of the various parts is effected as follows: Oil is forcedinto the grooves of the shaft occupied by the rods fand is returnedafter lubricating the shaft d and its attachments by means of theconduits m and o.

While I have shown my invention as applied to only one side of a vessel,it will be understood that one propeller is situated upon each side ofthe ship, or, if found desirable, a plurality may be placed upon eachside of the ship.

It is obvious that many changes might be made in the details of my saidinvention without departing from the spirit thereof; but

What I claim, and desire to secure by Letters Patent of the UnitedStates, is-
